He ended things with the Cardnals because of non-stop touring and much needed breaks for all band members. Then, the Cardnals bass player died, which made the break string out much, much longer.
I don't see this turning into a tour or anything. If there's one thing Ryan's capible of, it's surprizing us with the unexpected. Let him come back on his terms, and not pressure this genius of our generation.
While we would love to see and visit you again on the road, Ryan, make sure you're healthy and intentions are pure!
